Class Three Levers

A lever is a beam free to pivot around a point, used to move a load. One of those levers is a class three lever. A class three lever is a lever with the effort in the middle in between the fulcrum and load. The load goes in the same direction as the effort when pushed on. The advantage gained with a class three is a directional advantage.

What Would we do Without Simple Machines

Life would be much harder without simple machines and especially without a class three lever. A class three lever provides a directional advantage and is used all the time in your regular life. You might not know that when your playing sports such as golf, hockey, tennis, baseball, and fishing you are using class three levers. In these sports a baseball bat, fishing rod, hockey stick, and a tennis racket all provide an advantage by having the hitting end move faster than your arm. As you can see life would be much harder without simple machines and especially without a class three lever.
